CVSS v3.1 |
| As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco networking engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76470 are related to incorrect calculation issues that are grouped under the Common Weakness Enumeration (CWE) Pillar CWE-682. |
| Incorrect calculation in API in Google Chrome on on Windows prior to 155.0.8059.39 allowed a remote attacker leveraging social engineering to spoof UI elements via a crafted Chrome extension. (Chromium security severity: Medium) |
| ZBar commit 2ea2ca58 contains an undefined-behavior vulnerability in the Code 128 decode6() function. When processing specially crafted Code 128 input, decode_e() can return -1 for an invalid edge pattern, and decode6() subsequently left-shifts this negative signed value while constructing the edge signature. The operation invokes undefined behavior and can terminate trap-mode UBSan builds with SIGILL, resulting in denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: cortina: Ack RX overrun interrupt correctly
The RX overrun interrupt is reported in interrupt status register 4, but
gmac_irq() acknowledges it using the RX descriptor error bit from status
register 0. For GMAC0 this writes the GMAC1 overrun bit, while for GMAC1
the shift leaves no bit in the 32-bit register.
Acknowledge the same per-port RX overrun bit that was detected. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/shrinker: Take a runtime PM ref before shrinking non-system memory
__xe_shrinker_walk() walks the SYSTEM and TT LRUs without a runtime PM
reference. Shrinking a bo outside system memory invalidates its GPU
mappings, which needs the device resumed, so while it is runtime
suspended the page table zap trips an assert and the TLB invalidation
returns -ENODEV:
WARNING: drivers/gpu/drm/xe/xe_bo.c:770 at xe_bo_move_notify+0x1fc/0x450 [xe]

Take a reference before walking a memory type other than XE_PL_SYSTEM
and stop there if it cannot be acquired. Reuse the shrinker's existing
acquire path, which resumes the device directly where reclaim allows
that and otherwise queues the PM worker for a later scan. Stop the walk
once the scan target is met, so a satisfied scan does not wake the
device. System memory is still reclaimed while the device is suspended.
Gate this on xe_device_is_l2_flush_optimized(), the same condition under
which xe_bo_trigger_rebind() issues the invalidation for a non-fault-mode
vm, so reclaim is unaffected elsewhere. The System CCS copy already has
its own reference in xe_bo_shrink().
Only a non-fault-mode vm can reach this, since a fault-mode vm requires
LR mode and that holds a runtime PM reference for the vm's lifetime.
Reproduced with igt@xe_madvise@dontneed-before-exec while the GPU is
runtime suspended.
v2: simplify needs_rpm check. (Matt)
retarget Fixes tag since the issue occurs with the non-fault-mode
path added by 4e7ebff69aed.
v3: handle this in xe_shrinker.c instead of xe_bo.c (Thomas)
v4: stop the walk once the scan target is met. (Sashiko)
v5: rebase on the freed page accounting fix. (Sashiko)
v6: reuse the shrinker acquire path so runtime pm can be resumed
directly instead of always queueing a worker. (Thomas)
v7: replace xe_pm_runtime_put() with xe_shrinker_runtime_pm_put(). (Thomas)

| Incorrect Calculation vulnerability in VillaTheme CURCY woo-multi-currency allows Integer Attacks.This issue affects CURCY: from n/a through 2.2.17. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: master: Do not treat master device as a duplicate target
i3c_master_search_i3c_dev_duplicate() searches the bus for another I3C
device with the same PID as the reference device. The search can match
master->this, causing the controller itself to be returned as a
duplicate.
Since the controller is not a target device, it cannot be a duplicate of
one. Exclude master->this from matching so that the function only
returns real duplicate target devices. |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: move quota_init qc iterator increment
Move qc++ from the loop body into the for-loop increment
expression in gfs2_quota_init().
This keeps iterator progression explicit and avoids mixing pointer
advance with duplicate-slot handling in the loop body. |
| Incorrect Calculation vulnerability in RTI Connext Professional (Core Libraries) allows Abuse Existing Functionality. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.0.0 before 7.3.1.6, from 6.1.0 before 6.1.*, from 6.0.0 before 6.0.*, from 5.3.0 before 5.3.*, from 5.2.0 before 5.2.*, from 4.1x before 5.1.*. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: scope session state changes to bound connections
ksmbd_all_conn_set_status() treats every connection whose transient
binding flag is set as belonging to the target SessionId. A logoff or
session replacement can consequently move an unrelated connection to
NEED_RECONNECT or NEED_SETUP.
Pass the target session itself and select connections using either the
connection-local session xarray or the session's permanent channel list.
Use the same association test while waiting for requests to drain.
Serialize session-wide status changes under request_lock and do not
overwrite EXITING or RELEASING. Protect the shutdown transition with the
same lock so a concurrent session update cannot revive a closing
connection. |
| In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: clear delay state when freeing policy data
iocg_kick_delay() turns sufficiently large debt into an explicit
block-cgroup delay with blkcg_set_delay(), setting blkg->use_delay to
-1 and incrementing blkcg->congestion_count. Clearing it again depends
on iocg_kick_delay() running from the period timer, the waitq timer or
the issue path.
ioc_pd_free() removes the iocg from active_iocgs and cancels its waitq
timer, and no further bios can arrive, so once it has run nothing is
left which can reduce the debt and clear the delay. The blkcg stays
marked congested for the rest of its life.
blk_cgroup_congested() then returns true for every task in that cgroup
and its descendants: page_cache_sync_ra() cuts readahead to a single
page, page_cache_async_ra() skips it altogether, and
__folio_throttle_swaprate() takes swap_avail_lock and schedules a
throttle on anonymous folio allocation.
Clear it explicitly, after the list removal and the synchronous
hrtimer_cancel() so that neither timer processing nor an I/O path can
re-arm it. The free callback can also see policy data which was never
attached to a blkg, hence the pd->blkg check. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid5: round bitmap stripes with sector division
raid5_bitmap_sector_map() aligns the array range to full RAID5 stripe
widths before converting it to component sectors. That width is
chunk_sectors multiplied by the number of data disks, and it is not
always a power of two.
Reproduce with a 4-disk RAID5, 1024-sector chunks, and three data disks.
The full-stripe width is 3072 sectors. For a one-sector write at array
sector 3072, correct rounding gives array range [3072, 6144), which maps
to component range [1024, 2048). The old round_down()/round_up() logic
instead gives [1024, 4096), which maps to [0, 1024).
Use sector_div() based arithmetic so the rounded range is aligned to the
actual RAID5 stripe width.
The deterministic mapper test now reports the fixed component range as
[1024, 2048), while the old mask-based range was [0, 1024). |
| As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Secure Adaptive Security Appliance Software, Cisco Secure Firewall Threat Defense Software and Cisco Secure Firewall Management Center Software engineering team has conducted a comprehensive internal security review.

The vulnerabilities tracked by CVE-2026-20335 are related to incorrect calculation issues that are grouped under the Common Weakness Enumeration (CWE) Pillar CWE-682. |
| snipe-it before 8.7.0 contains an incorrect calculation vulnerability in checkout request handling that allows authenticated users to corrupt the assets.requests_counter through duplicate submissions and cancellations without active requests. Attackers can repeatedly call cancel endpoints without active requests to drive the counter negative, or submit duplicate checkout requests to inflate the counter, misrepresenting pending demand in the admin queue. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: dw-edma: Serialize channel state checks
pause() and resume() read and update channel state without holding vc.lock,
while the interrupt handlers update the same state under it. Take the same
lock around those state checks so that request, status, and configured stay
consistent.
For example, pause() can observe EDMA_ST_BUSY right before the interrupt
handler completes the final descriptor and moves the channel to
EDMA_ST_IDLE, and then record EDMA_REQ_PAUSE on an already idle channel. No
further interrupt will acknowledge the request, and since issue_pending()
requires EDMA_REQ_NONE, the channel is wedged for good: terminate_all()
leaves the stale request behind, so even reconfiguring the channel does not
recover it.
issue_pending() already runs under vc.lock, but it tests configured before
taking it. Move that test under the lock as well, so configured, request,
and status are evaluated as one channel-state snapshot. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: chemical: sgp30: Handle IAQ thread creation failure
kthread_run() can fail and return an error pointer, but sgp_probe() stores
it and returns success, so the device is registered without its IAQ thread
and sgp_remove() later passes the error pointer to kthread_stop(). Return
the error from probe instead. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: nVMX: Always flush vpid02 on first use
Make sure vpid02 is always flushed on first use by setting last_vpid=0
when allocating vpid02. nested_vmx_transition_tlb_flush() will always
detect a VPID change on first VM-Enter after VMXON, because VPID=0 in
vmcs12 is not allowed if L1 enables VPID.
This avoids using stale TLB entries from a previous lifetime of the
VPID, that might have been associated with a different vCPU (or a
completely different VM).
Note that last_vpid is already being initialized as 0 when the vCPU is
created, but it is not reset when vpid02 is freed on VMXOFF. Hence, the
problem can only occur if L1 does VMXOFF -> VMXON, runs an L2, and KVM
happens to reuse a VPID that has TLB entries on the physical CPU. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SEV: Forcefully invalidate SNP VMSA if its backing gmem page is zapped
Wire up a gmem_invalidate_range() call for SNP VMs, and use it to force
vCPUs to reload/recheck their guest-provided VMSA if the backing gmem
page is being invalidated, e.g. is being PUNCH_HOLE'd. Use the same core
logic to handle invalidations as VMX does for the APIC-access page, as the
two concepts are nearly identical: shove the physical address of a page
into the vCPU's control structure:
1. Snapshot the invalidation sequence counter
2. Grab the pfn (from guest_memfd in this case)
3. Acquire mmu_lock for read
4. Re-request reload if retry is needed, otherwise commit the change.
Note, the re-request action in #4 is necessary as KVM's retry logic is
fuzzy, i.e. can get false positives. If the guest_memfd page has been
dropped, at some point a subsequent reload will fail to get a PFN from
guest_memfd, and KVM will fail KVM_RUN. If the retry was due to a false
positive, KVM will retry until there are no relevant MMU notifier events
(and will retry in the "outer" loop, i.e. will drop locks and resched as
needed).
Note #2! Take care to invalidate the VMSA when a relevant memslot is
DELETED or MOVED, as invalidations in response to PUNCH_HOLE are predicated
on memslot bindings (KVM doesn't know what GFN range(s) to invalidate
without a binding). And more importantly, the VMSA mapping requires a
memslot, i.e. must be invalidated if its memslots disappears, regardless of
the state of the underlying guest_memfd inode.
Failure to invalidate the vCPU's control.vmsa_pa (which is checked by
pre_sev_run()) can prevent KVM from properly freeing the page as firmware
will reject the RMPUPDATE to reclaim the page with FAIL_INUSE if the vCPU
is actively running, i.e. if VMSA page is in-use. That in turn leads to an
RMP #PF on the next use, as the page will still be assigned to the SNP VM.

| As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco IOS XR Software engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-20275 are related to incorrect calculation issues that are grouped under the Common Weakness Enumeration (CWE) CWE-682. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/mm/ident_map: Use gbpages only where full GB page should be mapped.
When ident_pud_init() uses only GB pages to create identity maps, large
ranges of addresses not actually requested can be included in the resulting
table; a 4K request will map a full GB. This can include a lot of extra
address space past that requested, including areas marked reserved by the
BIOS. That allows processor speculation into reserved regions, that on UV
systems can cause system halts.
Only use GB pages when map creation requests include the full GB page of
space. Fall back to using smaller 2M pages when only portions of a GB page
are included in the request.
No attempt is made to coalesce mapping requests. If a request requires a
map entry at the 2M (pmd) level, subsequent mapping requests within the
same 1G region will also be at the pmd level, even if adjacent or
overlapping such requests could have been combined to map a full GB page.
Existing usage starts with larger regions and then adds smaller regions, so
this should not have any great consequence. |
